Simpsons Babies: The Sleuthenizer Walkthrough

Comic Book Guy: Interesting. Various characters are reverse-aging into babies, much as in classic Futurama episode 4ACV09.
Comic Book Guy: Although in that story the device was called a "Youth-a-sizer", not a "Youthenizer", so this is very, very different.
Lisa: Instead of nitpicking sarcastically, why don't you help for once?
Bart: Yeah! Like, tell us how superheroes would un-reverse the aging process.
Comic Book Guy: Well, let's see. In the movie Superman, the hero of the same name reversed Earth's rotation, causing time to run backwards.
Comic Book Guy: However, that's the third stupidest thing in history, behind two things Aquaman did that are too embarrassing to discuss.

Lisa: I should have come to you first, Professor Frink. Can you reverse the Youthenizer?
Professor Frink: Hmm. I once un-reversed an Oldening Ray, so the process should be similar. Stand back while I bloink the gizmodulator...
Youthenizer: BEGIN YOUTHENIZATION YET AGAIN
Bart: Oh no! Not yet again!
Baby Frink: Good glayvin, I'm a baby now? I've never seen a Youthenizer on such a hair trigger!
Lisa: Y'know, I'm just going to hide it behind a napkin to avoid any more accidents.
Baby Frink: That's all well and good, but I've lost my object permanence. So since I can't see it, it doesn't exist! Problem solved!

Lisa: *sigh* Everyone who tries to help just ends up in a soiled onesie of their own making. I've got no one left to turn to!
Bleeding Gums Cloud: Lisa, believe in yourself! Stop listening to smart people, and for no reason start listening to clouds that resemble deceased saxophonists.
Lisa: That is offensively stupid, pseudo-religious bunk! And it makes me feel better! Thanks to you, the clouds are beginning to lift.
Lisa: Hey, why are you lifting? Goodbyyyye!

Lisa: I find I often get ideas when I'm playing the saxophone.
Bart: That gives me an idea! Let's go ride our bikes so I don't have to listen to you play the saxophone.
Lisa: Okay. We're on our bikes now.
Bart: Yep. And we're riding past the teen center.
Lisa: Wow! We're suddenly covering a lot of ground, both on our bikes and in the plot.
Bart: Say Lis... teenagers are good with technology, right? Maybe that dork over there can help with the Youthenizer.
Teenage Smithers: Who, me?
Lisa: *gasp* Mr. Smithers?! You're a teenager now?!
Teenage Smithers: Ugh, don't ask. I got a partial blast from a hair-trigger, ivory-block Youthenizer. But you kids wouldn't know about that.

The Sleuthenizer Pt. 5

Auto starts

Lisa: We need your help, Mr. Smithers.
Teenage Smithers: Please, don't call me "mister".
Bart: Oh, right, on account of your confused sexuality.
Teenage Smithers: Say what? As a teenager, I'm simply not accustomed to being called "mister".
Teenage Smithers: Although come to think of it...
Lisa: Later! Right now we need to reverse the Youthenizer. It's here, in my bike basket.
Lisa: No, wait, that's my smart speaker. It's over in Bart's basket.
Teenage Smithers: Be careful with that! Mr. Burns was using it last week. I tried to run, but a glancing wave caught the edge of my left adenoid and made me a teenager.
Lisa: So Mr. Burns is behind this! I knew it all along!
Bart: You did? Then why are you conducting a painstaking investigation?
Lisa: It's how I do.
Lisa: Now let's put some music on the smart speaker and head for the power plant!
Youthenizer: BEGIN YOUTHENIZATION FOR NOT THE LAST TIME
Bart: Lisa! You've been baby-ized!
Baby Lisa: Oh God, this is terrible! I won't be able to play the saxophone again for years!
Bart: Hooray!
